I did not find any similar topics here so i thought it would fit nicely here:
New technologies are found every day all over the world and i am sure not all technologies find their way to Tesla. So therefore this topic.
Here are 2 interesting ones i found today:
I hope you will share your technological findings here to for Tesla to investigate if they can use it in our future cars. To make our dreams come treu
there are several threads which cover a lot of interesting technologies, you can use volkerize.com to search for them on this forum.
The first link you included is already covered here: http://www.teslamotors.com/en_EU/forum/forums/super-supercapacitor
The second link... well, to be honest... looks nice, I could imagine it in movie however I am not so sure about it for real life scenario...
You seem to be under the impression TM is using or in the market for cutting edge tech. Nothing could be wronger. It looks for best of breed proven tech and integrates it to best advantage. The whole is then greater than the sum of the parts; the parts are not the issue or crucial.
Next gen touch screen that you can actually feel?
Small electric accumulators lifetime significantly constrains the mass use elektromobiley in the world!
But out there!
Already have battery power for an indefinite period of use!
Such systems are already using Formula 1,
Detailed studies professor superflywheels execution Gulia.
Why in Tesla mobiles do not use superflywheels?
My guess is that they're mechanical, and if they fail the consequences could be disastrous.
If you visit a Tesla store, one thing that is not uncommon to see is people being amazed by the fact that there's "nothing" under the hood (or in the trunk) and then thinking the car is just some sort of mock up or something.
So to make people more comfortable and endulge their expectations, they should put a big one of these in the frunk of every Model S.
Or a hamster wheel...
How about this tech?
Tesla should tr to incorporate a generator into their their car :
As the thingy spins for the wheels add a magnet and copper coils to produce a electric current to power and charge the battery pack.
In my mind a car that is almost self-sufficient and a self-charging vehicle would almost have unlimited range, and the faster it goes the more power it makes in itself.
Thank you just an idea
Perpetual motion AGAIN.
This has been discussed and debunked several times dude, it's not happening.
Got the links handy Volker? I can't dig them out on my iPhone.
Enthusiast, stand on one end of a towel. Grab the other end and lift yourself off the ground. Report back when successful. 'Bye!
I wonder if Tesla considers using 3D printing to produce components of future models...
Some prognosticators are prognosticating that 3D printing will soon be the end of reliance on big foreign factories and suppliers. And since TM is gung-ho for vertical integration ...
Question: Will we see induction technology in the future have us drive electric cars without battery packs? I think this could be verry real if alroads had this tech in them but (second question) is it had or expensive to get it in to the roads?
Sure, road paving will be done by giant 3D printers on wheels, and they'll lay down the circuitry as part of the pavemen. Real soon now.
Actually not a bad idea, that one could work as high-tech road builder. Not quite same thing as creating small parts at home with 3D printer though. You need kind of factory on wheels for that.
I wonder when they start making pavement from carbon nanotubes...
(reacting to "real soon now", people overestimate short term development, and underestimate long term)
There are some awesome ideas here!
A special kind of paint is being developed. This paint has got the ability to turn sunlight into electricity (just like solar panels). This could be extremely helpfull for all Electric Vehicles. Because the car will be charging itself during daylight. I think this is a great idea. Don't you think so?
Please don't cross- and double-post. Almost everybody here reads every thread every day, usually several times.
I apologise for that.
There is a company called Endless Lip Technologies that has developed a new type of modular wheel assembly. The basic idea is that the assembly hardware is inside the pneumatic chamber, creating a whole slew of performance, cosmetic, and manufacturing advantages over what is available today.
I have met the team before and their patented technology has given them the ability to develop wheel assemblies that were previously unpractical to use and manufacture. They can actually make something similar to the Hankook Tiltread shown in an earlier post. Here's their website and Facebook page:
Opti-coat, It has already been applied to many Tesla's, it's a proven performer, and reduces the need for washing, so saving water. Tesla Service centers could source local competent detailers to apply it pre-delivery. There are many other products on the market that are available, but they could be best described as long life sealants(18-36 months), not coatings(Modesta, 22PLE, C Quartz, HD Nitro Seal....). Opti-coat has a lifetime warranty available. I have been using it since 2007, and I still see some of those vehicles on a regular basis(I am a detailer by profession), and they are still protected as they were the day I installed the Opti-coat.

Anything from dailykos is presumptively deluded. Flagged.
I have an idea in mind: what about equipping the tesla with a 230V AC Transformer with a max power of 3500W for example. Then u have a europe standart power outlet for every kind of 230V Machinery, Tools, or any other aplication on board. Would make for a good camping for example, when u have power for TV, Laptop, Musik for evenings party in holiday or whatever u like to run with it. U could certainly also make the Model S and upcoming cars compatible to the home electricity net to use the teslas batterie pack as Battery for ur home solar power plant or waterpower,windmill, whatever. So when the car is parked at home u just connect it to a plug in that connects car and house, in a way the 85kw batterie acts as source for ur 230V indoor AC net. Should not require much or am i wrong? all u need is a DC-AC converter and some kinda logicmodule that makes it work and customerfriendly to handle. maybe with options like "use batterie till its down to half capacity or something, i can quick imagine many options u could add"
in germany a company called sun invention (http://www.suninvention.com/) makes growing business in germany and europe these days. They produce solar panels that have a AC converter and a 30Ah LI Battery on board, and a logical contoler that toggles between direct delivery in ur flats or houses powergrid. When no power is "consumed" the batteries load up for night mode. such panels provide like 250W at 230V a single panel and the cells can be connected by another with simply plug in another. The first cell in line is then connected to a standart 230V wall adapter u normaly connect a TV to for example. over the 230V wall connector energie flow directly into comsumers powergrid and is used. No energy is delivered into the street line. No permits or concessions or authorisations needed. Such a system connected with a tesla`s battery as storage when car is parked at home would allow zero energy consumption from the electric companies network. can u follow my idea even tho my english is not perfect?
Imagine these 2 situations: u are on summer holiday and u have not much to drive around. Sun shines powerful for weeks but u have no use for the electricity all day that is coming from ur solar panels. By the other hand once u decide to wash dishes, clothes and running a pc at same moment the electric comsumtion comes to a peak and is higher then the output of ur solar panels. Instead of buying electricity from the company now imagine u could feed the peak moments with the car batterie. And the time when u not use much energy from ur roof solar panels or what ever, the "overflow" energy is saved in that batterys. If such a option would be included and i bet its technically quite simple to make it work like that, owning a Tesla car would been giving u one more really cool tool to have ur personal energy autonomy. As i believe that environmentally minded ppl are the first who are interested in the car anyway, this would make for another perfekt reason to get one.
Second idea is who hasnt ever had this problem...u are outdoors somewhere and nothing would be more practicable than have standart 230V Power for Tools, for Light at night, for Musik, for cooking, for refrigator. Camping ppl and owners of allotment gardens well knew that, and many buy gas powered electric generators just for that cases. How cool would it be if u have a huge mobile battery right in ur car, that easy has enough power for the garden party on weekend or for the camping week...would add another big bonus to Tesla Vehicles imho...
Yeah, your $5K worth of cells would save you $5 worth of electricity, if you park in the sun for a month. Nonsense.
I wonder how much would it cost if you go for cheapest, and not the best, IE. use thin film solar paint for roof. It would not generate much, but it wouldn't cost much either. Might be just enough to prevent charge loss when parked for prolonged time period, which could make it worth it.
What about magnetic suspension. Heard good things about it.
I have seen struts with generator heads on top that produce electricity as the car drives on irregular roads. Model S being a heavy car, it may be able to recover some nice amount of energy.
have a look:http://www.earthtechling.com/2013/09/regenerative-energy-car-tech-spread...
It can't recover much, otherwise it would not be able to move. Energy lost to suspension is just small fraction of rolling resistance.
Energy saving smart cruise control : Besides tracking the car in front, use predictive algorithms to minimize regen braking, and avoid disk braking. Swithc automatically from regen to coasting mode and back ... Useful in hilly terrain as coasting is more efficient than regen.
In highway driving can the car drive lower? Can the front ned be more aerodynamic? Rliminate some of the grills?
The wheel space undeneath could be made more aerodynamic. Add plastic panels near wheel wells. Eliminate turbulence.
Those improvements should be cheap. Add highway miles!
Coasting downhill gets you tickets. Can be more efficient, but not practical.
It already does, not really and can't do that.
Easy way to extend range: make smaller car. Model S is heavy and large. Not a good combination for efficient driving. For efficiency you can't do much better than they have already done for real world car like Model S.
I hope they at some point invent clear coating for windows that changes infrared to visible spectrum. That could make nighttime driving quite a bit safer. Being able to see wildlife, cyclists and pedestrians way before your lights illuminate it could save lives.
I really like the ways you guys think! There are some great ideas here like the magnetic suspension!
A Self cleaning car would disrupt .
Good site . . . right topic for me . . . lets see how it goes?
I have been pondering how to get at least some juice back to the battery while the car is in FORWARD MOTION (i.e. 90% of the time) instead of while only during regenerative braking (i.e.approx. 10% of the time).
I'm Not Suggesting a Perpetual Motion Time Travel Machine Here . . . ok?
Just a way to capture enough energy from the Forward Motion of the motor driven wheels to send back a useful charge to the battery to slow down the constant depletion rate of the battery.
My current 2013 Elantra LTD has a 4 cyl. 1.8 148HP. The single alternator on my engine probably is costing me 2-3 HP at most.
With high quality bearings at each end who's to say how much drag could be saved and turned into HP ?
You could harness . . . belt drive / chain drive or even perhaps magnetically drive . . . 2 or even probably 3 alternators to each motor/wheel assembly and not suffer any noticeable loss in power. So two motors or four motors / two or three optimized alternators each . . . sounds promising to me?
I can remember holding a few alternators in my hands over the years and spinning the pulley by hand . . . not much to it.
Alternators have been around for many years and can be optimized in many ways if necessary. Nothing needs to be invented to take advantage of these and with todays onboard puter tech. they could be self-diagnosing . . . e.g. Wheel#1 / Unit#2 / #3 Diode Failure.
The equiv. HP of todays elec. motors is much greater than that . . . especially when multiple motors are used.
I suspect the elec. motor design that Tesla uses are made mostly for the long haul (perhaps 500K mi. or more lifetime) although the Model S is known to be as quick as a new Corvette.
If you want to see electric motors/cars made to high performance racing standards watch these . . . ENJOY.
Just Brutally powerful . . . 0 - 100mph in 5 seconds and now 219mph top speed (was 210mph). This Drayson car ( 2 vids below ) is suppose to be in the 24hrs of LeMans this June in France.
This one is awesome too and really has that powerful sound . . .
For Tesla to consider . . .
I wonder if there is any benefit to somehow adopt the use of this simple engine . . . not in place of their electric motors but to power an electrical charging system for the battery . . . both on-board and at home in the garage?
It is said to generate enough power to drive generators on boats?
Considering it runs off of any heat source that's pretty good?
Alternator is not free energy. A car motor is basically a huge alternator, when you regen it slows car down. It's the act of turning kinetic energy to electricity that is making that braking.
Same thing would happen with smaller alternators, just in smaller scale. You basically drive with brakes on. And since you can never get perfect conversion ratio you just end up losing energy.
What you basically suggest is this:
battery -> motor accelerating the car -> alternator braking the car -> battery.
That's far less efficient than
battery -> motor accelerating a bit less.
Timo my intent is to say . . .
A) Battery > motor accelerating the car & driving the alternator(s)
>some kind of charge being sent back to battery.
B) Regen can still be used separately if it is worth it in terms of energy captured / cost effective and not in the way of A)above.
* I mean to suggest that the alternators be used predominately in the forward motion of the car although my understanding is that alternators work in either direction.
Thanks for helping me to be more clear.
Oh and clearly I do not have a firm understanding of the regen system or it's limitations?
How much charge it sends back to the battery is probably proprietary info. and obviously not enough or the batt would not be in a state of constant depletion.
McGov your idea is perpetual motion unfortunately. If the wheels have to also spin your alternator, and it generates a tiny bit of electricity, then it'll slow the car down a tiny bit more than normal, so you'll need to use a tiny bit of extra power to get the normal performance. It cancels out.
Regen breaking is as timo said , same as ebay you're saying on a bigger scale.
There is debate about how much generating the wheels should do when your foot is off the accelerator. Tesla has a solution that is really liked by many people. (Many (most?) cars don't regen at all until you press the brake - which has another side effect of having the brake pedal activating 2 separate braking systems and not being as smooth.)
I think part of what you wrote was better ball bearings to reduce friction- that would always help (without needing an alternator), but easier said than done.
"Same as ebay you're saying" should say "same as what you're saying"
Your question about how much energy goes back to the batteries is interesting. EVs have a greater benefit in city driving because your main drain is all the stop-starting, so you get a lot back from regen braking. That's why hybrids are effective. But it's not 100% by a long shot.
I think one of teslas secrets is that the regen is limited by the motor size. Or in other words the faster electric acceration a tesla can achieve than other EVs and hybrids ALSO means tesla can regen larger amounts than others.
So to extend your question - given that a tesla regenerates by taking the foot off the accelerator, does the brake pedal increase regeneration to its maximum? Or just have the default regen plus braking?
@mcgov51, your A and B are not separate things. That's the point. Alternator, when it is creating power, brakes the car. If you use them you are driving brakes on and losing energy, not gaining any.
@grega, my understanding about Tesla cars is that brake pedal has no connection to regen. KISS principle.
@Timo, yes that's my understanding too. And I agree with KISS.
But if a Model S did maximum regen, how much more energy would it get back? If you drive effectively with one pedal of course it should make no difference… ?
I think that the display on the dash gives the hint. Regen can be counted on to get roughly 30-50% energy back. And it varies all the time, dependent upon speed, wind resistance, and terrain.
Timo: I love your description of what amounts to a 'Perpetual Stopping Machine'. ;-)
Bah, what is needed is a return to analogue controls. Turn a big dial to the right for more heat. No more searching menus, finding stupid buttons or screen inputs while driving with the sun glaring on a dirty germ-infested screen.
Analogue is unknown to many younger people, those who only know the dirge that is digital. They will ooh and agh over the elegant design and interface, so much less WalMart than screens and icons...
Analogue controls for most functions (not GPS, etc) and access to a cheap fast charge at electric stations everywhere. That is all that is needed.
I'm sure those who want analog controls will just save up for a Rolls-Royce or Bentley instead.
Tesla's regen is software limited. You can have 0-100% of torque if regen.
If it had front wheel drive and 100% (or even substantially less), you would
actually get very agressive ABS front braking with the motor.
And no, it isn't a trade secret or anything like that. They set the regen with eye on comfort and safety (not to turn the car around on slippery road).
